Jest vs pre-commit by Yelp: What are the differences?
Jest: Painless JavaScript Unit Testing. Jest provides you with multiple layers on top of Jasmine; pre-commit by Yelp: A framework for managing and maintaining multi-language pre-commit hooks. If one of your developers doesn’t have node installed but modifies a JavaScript file, pre-commit automatically handles downloading and building node to run jshint without root. Pre-commit is a multi-language package manager for pre-commit hooks. You specify a list of hooks you want and pre-commit manages the installation and execution of any hook written in any language before every commit. pre-commit is specifically designed to not require root access.
Jest belongs to "Javascript Testing Framework" category of the tech stack, while pre-commit by Yelp can be primarily classified under "Git Tools".
Some of the features offered by Jest are:
- Familiar Approach: Built on top of the Jasmine test framework, using familiar expect(value).toBe(other) assertions
- Mock by Default: Automatically mocks CommonJS modules returned by require(), making most existing code testable
- Short Feedback Loop: DOM APIs are mocked and tests run in parallel via a small node.js command line utility
On the other hand, pre-commit by Yelp provides the following key features:
- node
- python
- ruby
Jest and pre-commit by Yelp are both open source tools. Jest with 26.1K GitHub stars and 3.53K forks on GitHub appears to be more popular than pre-commit by Yelp with 3.04K GitHub stars and 231 GitHub forks.
As we all know testing is an important part of any application. To assist with our testing we are going to use both Cypress and Jest. We feel these tools complement each other and will help us get good coverage of our code. We will use Cypress for our end to end testing as we've found it quite user friendly. Jest will be used for our unit tests because we've seen how many larger companies use it with great success.
Postman will be used to do integration testing with the backend API we create. It offers a clean interface to create many requests, and you can even organize these requests into collections. It helps to test the backend API first to make sure it's working before using it in the front-end. Jest can also be used for testing and is already embedded into React. Not only does it offer unit testing support in javascript, it can also do snapshot testing for the front-end to make sure components are rendering correctly. Enzyme is complementary to Jest and offers more functions such as shallow rendering. UnitTest will be used for Python testing as it is simple, has a lot of functionality and already built in with python. Sentry will be used for keeping track of errors as it is also easily integratable with Heroku because they offer it as an add-on. LogDNA will be used for tracking logs which are not errors and is also a Heroku add-on. Its good to have a separate service to record logs, monitor, track and even fix errors in real-time so our application can run more smoothly.
